Well, I'd also say that as society continues to get more complex we're exposed to more and more previously-unknown substances, chemicals, and compounds. Kids used to play in the DDT mist sprayed by trucks. How many DDTs are there right now that we don't know about? I'd guess a whole lot.
Ultra and highly processed foods are terrible for us. Consuming so much more sugar than in nature seems to be bad for glucose intolerance. I love bacon but I try to resist ever having any. Don't buy meats with nitrates.
We do have way more cancers, a big reason we know about is our food choices. We don't even know the impact of hard things to measure yet, like the impact of all these things on our gut biology. It's not a new discovery that eating a lot of sugary foods leads to greatly increased diabetes, and now we are learning more about how artificial sugars have their own impact. So basically, it's increasingly obvious that artificial sugar drinks are not good for you too, maybe in different ways than "natural sugars".

That is no way to live.
In general, you should think about risk management, not exclusion. Have your bacon as a bi-monthly treat, and splurge for some high quality bacon at the butcher.
I remember seeing a video of a talk where the host asked who was managing their health by going partially or fully vegetarian. Lots of raised hands. Then he asked who was sitting or standing still for extended amounts of time. Even more raised hands, including almost all of the previous group. And that’s a higher cancer risk than meat eating :)
In the name of sanity, let’s all avoid “biweekly” and “bimonthly”. Just say twice a X to be clear. Pretty funny how the dictionary claims to be largely neutral by only reflecting the cultural ambiguity. I want an f-ing opinionated dictionary that says: avoid this ambiguous word!
It is not increasingly obvious that artificial sugar drinks are bad for you, and the cancers linked to nitrates are also down significantly in the US over the last 40 years. That's certainly not because people are eating less bacon, or because grocery store bacon has less nitrates in it ("nitrate-free bacon" is a fraud).
